Historical context
Precision & Scientific Horology (1750 – 1850)
Harrison solves longitude; Mudge invents the lever; Breguet's Paris workshop defines the modern watch.
The age of escapement invention: cylinder, duplex, lever, detent and many experimental escapements; compensation balances and fine finishing.

Atlas type guide
Clock and watch movements
The movement is the mechanism of a clock or watch, without its case and dial. It consists of the power source (weight or mainspring in its barrel, sometimes with a fusee), the going train of wheels and pinions, the escapement and oscillator, the motion work that drives the hands, and in many cases additional trains for striking or complications.
From the eighteenth century watch movements were increasingly produced in stages: Swiss and French ébauche makers supplied rough movements that finishers, repasseurs and retailers completed and signed. Calibre numbers — first used systematically by American and Swiss factories in the nineteenth century — make it possible to identify movements, find spare parts and date watches.
What to look for
- Plate and bridge layout: full plate, three-quarter plate, Lépine bar calibre, bridges and cocks.
- Jewel count and whether jewels are set in chatons or rubbed in.
- Signatures, calibre and serial numbers on the plate or under the dial.
- Finishing: Geneva stripes (Côtes de Genève), perlage, bevelled edges, blued screws.
- Fusee and chain, going barrel, or electrical components.
Dating clues
- Full-plate English movements dominate before c. 1850; three-quarter plate and Lépine calibres after.
- Jewelled movements spread after Facio and Debaufre's patent of 1704, mainly in English work until c. 1800.
- Calibre numbers and factory serials allow close dating for industrial production after c. 1850.
